Unionfs: remove useless debugging messages

Unionfs: handle whiteouts more efficiently in filldir
If we cache a dirent for file "foo", and then it gets deleted, then we look
for a ".wh.foo" whiteout entry in the same dirent cache. But our dirent
cache strips the ".wh." prefix, thus looking for an entry named "foo" whose
filldir_node->whiteout should be 1 instead of 0. In that case, don't
display an incorrect printk message that the file system may be corrupt,
but set that filldir_node->whiteout to 1.

Unionfs: Simplify unionfs_get_nlinks
Since we set the right value for d_type in readdir, there's really no point
in having to calculate the number of directory links. Some on-disk
filesystems don't even store the number of links for directories.

Unionfs: unionfs_create rewrite
The code was hard to follow and violated some invariants (e.g., never modify
a read only branch, and always create on branch 0).

Unionfs: imported fixes from korg branch's take-3 series
- removed EACCES/EROFS text from issues.txt
- updated sioq.[hc] copyright dates to 2006 (not earlier)
- added small XXX comment to xattr copyup code (selinux CAP_FOWNER stuff) to
say that entire copyup code should be moved to SIOQ.
- copyup_xattr: renamed name_list_orig -> name_list_buf
- multi-line static inline unionfs_xattr_kfree
- rewrote unionfs_interpose a bit cleaner (no backward goto's, better
variable names, use small util fxn, etc.)
- introduced CONFIG_UNION_FS_DEBUG instead of hand-editing makefile
- unionfs_mntget/put cleanups
- bug fix to is_robranch_idx (thanks to Patrick Aussems). Fixed bug #571.
